A Rust library for reading and writing Nintendo's BCSV/JMap format This format is used by Super Mario Galaxy and some other games

Quick Start

use lib_bcsv_jmap::{from_file, to_csv, smg_hash_table_with_lookup, IoOptions};

// Create a hash table with known field names
let hash_table = smg_hash_table_with_lookup("hashtable_smg.txt").unwrap();

// Read a BCSV file
let jmap = from_file(hash_table, "scenariodata.bcsv", &IoOptions::default()).unwrap();

// Print some data
println!("Entries: {}", jmap.len());
for entry in jmap.entries() {
    if let Some(name) = entry.get_string(jmap.hash_table(), "ZoneName") {
        println!("Zone: {}", name);
    }
}

// Export to CSV
to_csv(&jmap, "output.csv", None).unwrap();
